valency electron of Fe is???
Answers
Answer:
Iron (Fe) has an atomic number of 26, i.e. has 26 electrons. The energy of 4s and 3d orbital is similar (4s has slightly higher energy). ... Now, iron exhibits 2 valence states of +2 and +3. When iron loses the 2 4s electrons, it attains a valency of +2.
